    Biophysical and NMR studies of M-PMV protease have indicated that in the absence of substrates or inhibitors M-PMV PR should fold into a stable monomer, but the crystal structure of this protein could not be solved by molecular replacement despite countless attempts. The solution was obtained in mr-rosetta using a model constructed by players of the game Foldit. The structure shows a monomeric protein, with the N- and C-termini completely disordered. The flap loop has an unusual curled shape and a different orientation from both the open and closed states known from dimeric retropepsins. This structure provides important information for the design of dimerization inhibitors of retroviral proteases.
